Abstract

PURPOSE:To see the contents of a document already stored at the time of inputting a new sentence without enlarging the capacity of a collection memory by providing a specific display device and a display control means. CONSTITUTION:Data such as a character, a symbol is inputted by an input means and document data is stored in a text memory. In the collection memory, the data from the input means or he text memory is stored and the data can be edited. The display control means displays the data stored in the collection memory in the area capable of editing of the display device and displays the data stored in the text memory in a data display area. Therefore, as the collection memory, a capacity corresponding to the area capable of the display device is completely required to save the capacity corresponding to the data display area. Since a display is executed not only on the area capable of editing but also on the display area, the quantity of the display which can be recognized by an operator is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a document processing device, and more particularly to a document processing device having a function of editing stored documents.

(Prior Art) Conventionally, in this type of document processing device, for example, an electronic typewriter, when a document stored in a text memory is called up and edited, a document near the desired correction part is read out and stored in a collection memory. Furthermore, the data in the row corresponding to the contents of the collection memory is displayed on the display. This allows the operator to perform editing work by modifying the collection memory while looking at the display.

(Problems to be Solved by the Invention) In the conventional document processing device, data in a row corresponding to the contents of the collection memory is displayed on the display. For this reason, when the display is made large (for example, a multi-line display type), there is a problem in that it is necessary to increase the capacity of the collection memory that stores data corresponding to the display contents.

On the other hand, if the display is made smaller (for example - line display type), the capacity of the collection memory will be smaller, but it will not be possible to view the contents of the already stored sentences when inputting new sentences. , there is a problem that the relationship and layout between the previous sentence and the newly added sentence become unclear.

(Object of the Invention) An object of the present invention is to enable the user to view the contents of a previously stored sentence when inputting a new sentence, without increasing the capacity of the collection memory, and to To provide a document processing device that improves workability when editing a stored text by clarifying the layout and relationship with added text.

(Means for Solving the Problems) As shown in the functional block diagram of FIG. 1, the document processing device according to the present invention includes an input means for inputting data such as characters and symbols, a data display area, and an editable data display area. a display device having an area, a text memory that stores document data, a collection memory that stores data from the input means or the text memory and can edit the data, and an editable area of the display device that stores data in the collection memory. display control means for displaying the data stored in the text memory in the data display area.

Preferably, the display device is composed of at least two lines and the number of displayed characters is smaller than the number of characters in one printed line.

(Operation) The document processing device according to the present invention allows the input means to input characters and
Data such as symbols are input, and document data is stored in the text memory. Data from the input means or text memory is stored in the collection memory, and the data can be edited. The display control means displays data stored in the collection memory in an editable area of the display device, and displays data stored in the text memory in a data display area.

Therefore, it is sufficient for the correction memory to have a capacity corresponding to the editable area of the display device, and the capacity corresponding to the data display area can be omitted. On the other hand, since the information is displayed not only in the editable area but also in the data display area, the amount of display that can be recognized by the operator increases.

(Effects of the Invention) According to the document processing device according to the present invention, since it is equipped with the display device and display control means as described above, it is possible to input a new sentence without increasing the capacity of the collection memory. You can now view the contents of documents that have already been stored. Therefore, the relationship and layout between the previous text and the newly added text are clarified, and workability during data input and document editing is improved.

The display CPU 71 reads display data corresponding to one line of data in the text memory 61 indicated by the upper line display pointer 65 and data in the collection memory 62 from the character generator 72,
The display data is output to the display controller 73. The display controller 73 writes display data into the upper row display data section 74a and the lower row display data section 74b of the display RAM 74, and at the same time outputs a display signal according to the display data to the LCD 75. By this, L
The CD 75 displays characters already stored in the data display area 76 (upper line), and adds new sentences or corrects already stored sentences in the editable area 77 (lower line). Display sentences within the range.

Next, a control flowchart of this embodiment will be explained based on FIG. 4.

In FIG. 4(a), this control is started when the typewriter 1 is powered on, and in step S1 (hereinafter simply referred to as Sl and other steps are treated in the same way),
The control program stored in the program memory 51 of the ROM 50 is read to the CPU 40, and general initial settings such as setting the cursor position pointer 64 to the first digit are executed. Next, move to 32 and move the upward display pointer 6
5 is set at the beginning of the last line of the text memory 61.

In the next step 53, the contents of the display RAM 74 are displayed on the LCD 75. In the data display area 76 of the LCD 75, the last line of the text memory 61 indicated by the upper line display pointer 65 is displayed for a maximum of 40 characters from the beginning of the line. However, if there is no data in the text memory 61,
Nothing is displayed in the data display area 76. Further, data in the collection memory 62 is displayed in the editable area 77. However, if no data exists in the collection memory 62, no data is displayed in the editable area 77, and only the cursor 78 is displayed in the first digit. In S4, the process waits for key human power, and if there is key human power, the process moves to S5.

In S5, it is determined whether the input key is the character key 10 or the space key 11. In S6, it is determined whether the input key is the cursor movement keys 13 to 16. In S7, it is determined whether the input key is the return key 2. to judge. If the input key is not one of these keys, the process moves to S8 and another input key is pressed.
After executing the key processing corresponding to , the process returns to S3.

If the input key is the character key 10 or the space key 11, the control moves from S5 to 89 in FIG. 4(b).

In S9, the input data is stored in the collection memory 62, and in S10, the content corresponding to the input data is printed on a printing paper by the printing mechanism PM. Then, in step 311, the input data is set in the lower display data section 74b of the display RAM 74, and then the process returns to S3. As characters and spaces are input one after another, the input data is stored in the collection memory 62 based on the processing in steps 89 to S11, and the input data is displayed in the editable area 77 of the LCD 75 (Fig. (a)). If you continue to enter characters and spaces after the cursor 78 moves to the rightmost position,
The cursor position pointer 64 is incremented by 1, and the display contents of the editable area 77 are scrolled to the left.

After inputting one line of data, press the return key 12.
When is pressed, the control moves from S7 to 312 in FIG. 4(d). At 312, the contents of the collection memory 62 are stored in the text memory 61.

Next, in 313, the upward display pointer 65 is changed to one line down. As a result, the data in the text memory 61 set in the upper line display data section 74a of the display RAM 74 is shifted down one line.

That is, the text memo IJ6 from the collection memory 62
The data newly stored in No. 1 is set in the upper display data section 74a of the display RAM 74. And 31
In step 4, the collection memory 62 is cleared, and in step S15
After performing line feed processing at , the process returns to step 33. The data newly stored in the text memory 61 is displayed in the data display area 76 of the LCD 75, and the cursor 78 is only displayed at the first digit in the editable area 77 (FIG. 5(b)). .

When you want to move the cursor 78 to a point that requires correction in order to correct data already stored in the collection memory 62, or when you want to move the cursor 78 to a point that needs correction in order to correct data already stored in the collection memory 62,
If you want to display it on 7, press cursor movement keys 13-1
Press 6. The control is from S6 to 316 in FIG. 4(c).
to move to. In S16, it is determined whether the input key is the left/right cursor movement key 13, 14 or not. If the input key is the left/right cursor movement key 13.14, then SL"7
, and the input key is the vertical cursor movement key 15.
．． If it is 16, the process moves to S18. In S17, the cursor position pointer 64 is changed within the editable area 77 according to the input key instruction, and then the process returns to S3. On the LCD 75, only the cursor 78 is displayed while leaving the data in the editable area 77 unchanged.

On the other hand, in 31B, the upward display pointer 64 is changed according to the input key. That is, if the cursor up movement key 15 is used, the up line display pointer 64 is decremented by one line;
At the same time, the data in the text memory 61 that was displayed in the data display area 76 is stored in the collection memory 62. On the other hand, if the cursor up movement key 16 is used, the up line display pointer 64 is incremented by one line. Furthermore, if there is data in the text memory 61 for the next line, that data is simultaneously stored in the collection memory 62 and displayed in the editable area 77. Subsequently, the cursor position pointer 64 is set to the first digit, and the cursor 78 is displayed at the first digit. after that,
Returning to S3, a corresponding display is performed on the LCD 75 (FIG. 5(c) or (d)).

When the desired correction is completed by moving the cursor and inputting characters and spaces, the return key 12 is pressed. As a result, the process shown in FIG. 4(d) is performed again as described above, and the corrected data is stored and printed.

As explained above, according to this embodiment, since the display device and the display control means as described above are provided, the capacity of the collection memory 62 does not need to be increased (when inputting a new sentence). You can see the contents of sentences that have already been memorized.

The relationship and layout between the previous sentence and the newly added sentence are clarified, and workability when editing memorized sentences is improved.

Note that the LCD 75 is not limited to a two-line display, and may be capable of displaying three or more lines.

Further, the capacity of the collection memory 62 is not limited to one line, but may be two or more lines. However, at least L
The line capacity is smaller than the capacity corresponding to all display lines of the CD 75.
